To all whom it may concern:

Be it known that 1, CHARLES F. GARLSON, a citizen of theUnite'd States,and a resident of South Bench in the county of Saint Joseph and State.of Indiana, haveinveuted certain new and useful Improvements in Flows;and I do hereby declare the followingto he afull, clear, and exactdescription of the invention, such as will enable others skilled the art"to which it apprtains to make iandiuse the same; a

This invention relates to improvements in plows and more particularly toattaclunents therefor. I r very common difliculty in the plowing of"some characzters of soil, -,particularly marsh la'hdf-is that thefurrow slices fail to some in close contact with each other and thuspermits the formatioiiwof crevices from which} vegetation may protrudeand in which undesiredvegetation may grow, and leaving the plowed groundin a rough and uneven condition. V

One object of my inven tion is to proi ide means to overcome theobjections above mentioned and to this end, to provide means whereby thefurrow 's'lioesmay be caused to lie comparatively fiat agaihst eachother and closely together thus causing the plowed ground to present acomparatively level sur- :tlace; eliminating th'e valleys or crevices socommon in plowed ground where the furrow slices" lean againsteach-other;

Affurth'er objeotisto provide-a plo'w structure which will operate, notonly to cause vegetation tohe hurie'dunderthe fun row slices but also"to olo'seathe 'creviees or valleyssuch asheretofore found in plowedgrmin'd and thus preclude the growth of undesired vegetation between thefurrow slices. 7 p I A further object is to provide a plow withineanswhich, in addition to effecting "the results 'above explained, willoperate to so widen the "furrowth'atthe wide wheels of a tractor orWheels with extensionfrims connected with the ploim will be permitted toiaiu 'o nr the laotthm' otthe furrow.

'se and Qtil'ie'r obje'etsi view, the invention"e nsists in "'C'ftad ilnovel .Ee'atm es of construction yhii'd eoiiibiiiations" of p arts.a'slier'einafter set forthiend pointed out in the cla'ims' stew'showing an embodiment of my invention;

The .Iandside myeomprises-a bar 3 projectingrearward-1y from theshare, and a landsidewea-rrplate 3secured to saidbar. The shoe iniayhe made hollow and bolted tothe landside bar 3 saidshoe being shouldered at l to-overlie? the rear end of thelandside barso that the outer-face: align with the outer face of the lan'dside wezirt plate-and the upright wall of the shoe is shouldered at l 'to receivethe rear end of said wear plate. Afrog or landside bar andmoldboardmaybe trace hyjmea-hs'of suitable rods or bars 6;, 6?. 4

A ourvedf brace 7 is secured to the landbolted to both, and one endportion 7 of this brace may oonstitute a portiolibf the;

means for securing the" share to the moldboard.

y A bar 8,, preferably angular incrosssec- V tion', is pivotalljrconnected to the brace 7 throti'gl'i the medium of an arm 9 rigidly andprovided with an angular portion 'pivoted to said braceat 10'. To onesideof the bar '8", a wing or blade 11 is rigidly secured; and has ageneral tapering shape with one Nit, isirieiwe dofo nivnn ofiinnnn aside bar 3? andto the inoldhoa rd and'is'" secured to thefor'wardportion of said her J0 i edge in alignment with the outer faceof said, 5

hair. Thewing or blade is so bentthat the portion thereof which extendsreal-weirdly beyond the bar' 8 marks a compoundcurve, 'as' indicated fatl2;said Wing" "or blade occupying a position somewhat inwardly removedfrom the back of thenioldhoard as that of theflower edgejnof thelandside (see in the ho'ttoniof the: furrowkmade' by the indicatedinFigUreQ of thedrawing. It r ,wili he -ohserved'that thefimejor portiorof the lower edge 3 of the; wing? 01* "blade 2 is in substantially thesame horizontal 1 plane 7 as 5 *Fi'grS) andwrllttherfore occupy apositionplow, andisaid wing; oncbla de is of such eer-. 1 endijsisslclpdsedthatit illproject 1 10f flit slice and leveling the same.

rearwardly beyond the inoldboard and its rear portion caused to projectseveral inches laterally beyond the plane of the rear eX- tremity of theshare, as will be evidenced by reference to Figure 2 of the drawing, andit will therefore operate to push the furrow slice laterally after itshall have been turned by the mold board.

The bar 8 of the wing or furrow slice crowding member 11 being pivotallyconnected at its forward end to a part rigid with the plow: structure(the forward brace 7) ,said wing or pusher is capable of lateraladjustment relatively to the mo-ldboard, and

it is held rigidly in the position to which it may be adjusted by meansof adjustable cross braces 13, 1%. The cross brace 13 may be curved andcomprise two members 13 and 18,.the former being secured to the landsideand the latter to the bar 8 of the wing or crowding member 11, and eachof said members may be provided withaplurality of perforations toreceive bolts 13 by means of which said members maybe secured togetherat the desired adjustment. The cross brace 14; comprises two perforatedmembers 1%, 14 secured together at the desired adjustment by boltsll,one end of the brace member 1 f being attached to the rear portion ofthe shoe 4: and the other brace member 14' being adjustably attached toan angle piece 141E secured to the wing or crowding member 11. In orderto insure the rigidity of the wing or pusher 11 and to guard againstpossibility of vertical displacement thereof when in use, a twistedbrace 10 is secured at one end to the rear portion of the moldboard andat its lower end, said brace is adjustably connected with a flange onthe member 13 of the intermediate cross brace 13.

A supplemental wing 16 may be provided at the rear end of the mold boardto assist in forcing over the top portion of the furrow Thissupplemental wing is connected with the moldboard by bolts 17 and 18,the former passing through a hole in the forward portion of said wingand through the moldboard, and the other bolt 18 passing through a slot19 in the wing 16 and through the mold board, so that the angularity ofsaid wing may be adjusted.

The operation of the plow provided with my improvements is as follows iLet it be assumed that the plow is such as will out a twenty-inchfurrow. The wing or furrow slice crowding member will be so adjustedthat its rear portion will project laterally approximately four inchesfarther than lateral extremity of the rear end of the share. The wingwill'then operate to crowd the furrow slice laterally an additional fourinches, thereby leaving twenty-four inch furrow, After the first furrowshallhave furrow slice as it would do if the furrow had not been widenedby the operation of the crowding member. The furrow slice having beendeposited flatly into the furrow, the crowding member will now operateto push the furrow slice laterally, crowding it closely'to the previousfurrow slice, closing the valley or crevice between said furrow slices,leaving the surface of the plowed ground comparatively level andestablishing a twenty-four inch furrow to receive the next furr w slice.Vegetataion will be dragged under when the tweni y-inch furrow slice isdeposited in the twenty-four inch furrow and as the valleys or crevicesare closed when one furrow-slice is crowded over to the previous furrowslice, the growing of rank or undesirable vegetation between the furrowslices will be precluded. Furthermore, my improvements insure a furrowof sullicient width to permit the extension rim of a tractor wheel or awide tractor wheel to run on the bottom of the furrow.

Various changes might be made in the details of construction of myinvention with out departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailshercin set forth.

Having fully described my invention what I claim as new and desire tosecure by Lctters-Patent, is
